wrnn FEEDING Ann ou'r'rrne MACHINE.

Application filed .Tune 19, 1926. Serial No. 117,020.

This invention relates to a wire feeding and cutting machine such as is used to feed wire from a coil and straighten or form it and cut it into lengths; and has for its main object and feature the provision of means for feeding it more uniformly than heretofore and to cut it into variable lengths.

In the accompanying drawings the invention is shown in a concrete and preferred form, in which Fig. 1 is a side elevation of a machine embodying one form of the invention;

Fig. 2 is a top plan view of Fig. 1; and

Fig. 3 is a sectional view on the plane of line 3-3 of Fig. 2.

1 indicates a wire gripping member of known construction and 2 is a wire spinner of known form rotatable by means of pulley 3 or otherwise. Both the gripping member and the spinner are mounted to reciprocate on framework 1 and, as is usual in machines of this character, the gripping member grips the wire. and feeds it forward during its feeding stroke and then releases the wire and returns to take a new grip on the wire; and the spinner likewise moves forward on the feeding stroke of the wire, but at less speed, say, one half, than that of the gripping member, and then returns toits initial position. During the forward movement of the wire the spinner acts to straighten it.

It is customary to effect the reciprocation of the gripping member by means of a crank, but, as the throw of a crank is variable, the wire is not fed forward with a uniform movement. It is desirable to obtain such uniform movement and, therefore, in order to compensate for the variable throw of the crank, I employ transmission means to drive the crank at a variable speed, whereby during its feeding stroke, the wire gripping mem ber moves at substantially uniform speed.

In the present instance, the means for effecting this are as follows: 5 and 6 are two elliptical gears in mesh with each other, the gear 6 carrying a crank pin 7 from which extends a connection 8, loosely attached to rock lever 9 pivoted at 10. Rock lever 9 has a link 11 connected to gripping member 1. Gear 5 may be driven in any suitable way as from a main shaft 12 by means of pinion 13 and spurgear 14.

Spinner 2 will also be reciprocated from the same source of motion, and, in the present instance, a link 15 extends from lever 9 to intermediate lever 16 pivotally supported at 17 on the framework, and from 16 extends a link 18 that connects to lever 19 pivoted at 20 and connected to slidable spinner frame 21. 7

Suitable means for cutting the wire into suitable lengths are provided, and, in the present case, these means take the following form.

22 is a cutting member, cooperating with stationary cutting member 23 through which latter wire 24 passes. Member 23 is mounted on rockshaft 25 arranged in bearings 26 and this rockshaft is operated intermittently by lever 27 and arm 28. Arm 28 is slidable in one or more guides 29 and is normally held in the position shown in Fig. 2 by spring 30. At its outer end, arm 28 carries a cam roller 31 adapted to be actuated by cams 32 on rotatable member 33.

Rotatable member 33 is turned intermittently by any suitable means such as by a Geneva stop motion 34:, one member of which is carried by shaft 35 on which gear 5 is located. It will be seen that the driving connections for the cutting member are operated once to each feeding movement of the wire and that, by spacing cams 32 a distance apart equal to the movement of the rotatable member, a given length of wire is cut off. Cams 32 are removable and it will therefore be seen that by removing every other cam the cutting member will be operated only once to every two feeding movements of the wire and thus different lengths of wire can be cut off by varying the number of cams.

I claim:

l. A Wire feeding and straightening ma chine, including a reciprocating wire gripping member to intermittently grip and feed wire, a reciprocatory wire spinner, a crank and connections to effect reciprocation of the member and spinner, the latter at a lesser speed than the former, and transmission means to drive the crank at a variable speed to compensate for the variable throw of the crank, whereby, during the feeding stroke, the wire gripping member moves at a substantially uniform speed and the spinner also moves at a substantially uniform speed but different from that of the gripping memher.

2. A wire feeding and straightening ma chine, including a reciprocating wire gripping member to intermittently grip and feed wire, a reciprqeetpry wire spinner, a, erank uniform speed and thespinner, else moves at and connections to effect re eipro cetien of the a substantially uniform speed different 10 member and spinner, the letter at a lesser fromthat of the gripping member.
